My understanding (from what I've read) is that it's genetic and that the cows carrying the A1 allele will produce milk containing the A1 protein. If they could remove the A1 protein from the milk I don't suppose they would need the DNA screening test.

Maybe they'll consider genetically modifying the DNA of A1 cows... 

 

Here's some more interesting tidbits on A2...

 

A study into heart disease death between the two cities of Belfast and Toulouse revealed the following. Both cities share near identical risk factors yet Belfast has nearly four times the number of deaths from heart disease. The calculated ratio of consumption of beta casein A1 between the two cities is 3.32:1 (Belfast :Toulouse). The ratio of heart disease death for males between 55 and 64 years of age is 3.33:1 respectively.

 

There are a number of African communities that suffer little to no coronary heart disease

but who include milk as an important part of their diet. The Zebu cattle from which they source their milk do not contain the A1 allele.

Tibetan highlanders whose source of milk is the Yak are also not prone to coronary heart disease. The Yak is free from the A1 allele. Their diet consists largely of Yak and goat milk, meat and potato.
